Sometimes we may see such an effect on a web page. When the mouse is placed on certain text or images, some changes will occur. This is actually a transition. It is relatively abstract in this way. So, here is what happens. Let’s introduce the animation effect of css3 transition.
Css3 transition is inseparable from the transition attribute. Transition is a transition animation on a web page. The gradual transition effect of changes is referred to as transition animation.
So, let’s take a look at how the transition attribute of css3 specifically implements the transition effect.
First, let’s take a look at the definition and usage of the transition attribute:
The transition attribute is an abbreviated attribute used to set four transition attributes.
transition-property: Specifies the name of the CSS property that sets the transition effect.
transition-duration: Specifies how many seconds or milliseconds it takes to complete the transition effect.
transition-timing-function: Specifies the speed curve of the speed effect.
transition-delay: Defines when the transition effect starts.
After reading the brief introduction to the definition and usage of the transition attribute.
Now let’s take a look at a css3 code to achieve the transition effect:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>小效果</title> <style type="text/css"> /*通配符重置浏览器默认的两个值, 对本文没有太大影响,不知道可以无视*/ *{ margin: 0; padding: 0; } .div1{ width: 400px; height: 100px; padding-top: 20px; line-height: 100px; margin:200px auto 0; text-align: center; font-size: 40px; font-weight: bold; font-family: "华文行楷"; background: #000; color:#F60; transition-property: all;/*变化的东西。all是所有*/ transition-duration: 1s;/*变化过程的时间*/ transition-timing-function: linear;/*linear是匀速变化*/ transition-delay: 0s;/*没有延迟变化*/ /*下面的是简写属性*/ /* transition:all 1s linear 0s; */ } .div1:hover{ text-shadow: 0px 0px 2px #fff, 0px -3px 3px #1EB, 0px -6px 4px #01DEFD, 0px -9px 5px #0BF, 0px -12px 6px #08F; } </style> </head> <body> <div>PHP中文网火焰字</div> </body> </html>
